9. The Red Cross
Weight: 205.07 carats

The Red Cross is canary yellow cushion-shaped diamond with weight of 205.07 carats. The rough stone weighed 375 carats and was found in Kimberly mines (South Africa) in 1901. The diamond was presented as a gift to the art sale held in London by Christies in 1918, on behalf of the British Red Cross Society and the Order of St. John. Another rare feature is that a Maltese Cross is distinctly visible in the top facet, hence the double appropriateness of its name, the Red Cross Diamond.
